Extension of Information and Decision-Making Support System for Earthquake Disaster Reduction

The extension of information and decision-making support system for earthquake disaster reduction depends on the state of arts of remote sensing (RS) technology, involving many fields of computer application skills and techniques. In this paper, first the importance of a key period after earthquake occurrence is discussed. Then a WebGIS based information and decision-making support system (the system) for earthquake disaster reduction is introduced. Meanwhile tested by an Ms5.1 earthquake in north-east China, the system showed the damage distribution maps, which include the comparison of isoseismals map and the damage of buildings map. Finally, several conclusions are presented.
